1966 Datsun Homer T641 Model
.
 
 
 The Datsun Homer has one of the most unfortunate vehicle names in history, and it also had a rather confusing life, being sold under several different names.
 The Homer began it's life in September 1961 as the T64, though interestingly it wasn't a Datsun back then. When the first Homer appeared it was as the T64 Prince Homer. The Prince Motor Company were a Japanese car manufacturer that can trace it's history back to 1926, when it began as Tachikawa Aircraft Company. Tachikawa were most famous for building the Zero bombers during the Second World War. After the war they started building cars under the name Tama, and then in 1952 they changed their name to Prince. Prince operated in opposition to Nissan, but in 1966 the Japanese Government orchestrated a number of mergers in order to create stronger companies that would be better equipped to ward off hostile takeovers from foreign companies. One of these mergers was between Nissan and Prince. After the merger the Prince name was slowly phased out, and Prince's products, such as the Skyline, Gloria and Homer, became Nissan or Datsun branded products.
The original Prince Homer T64 was in production from September 1961 until 1966, when Nissan and Prince merged. It was powered by a Prince G-1 engine, which was an OHV 1484cc 4 cylinder engine that produced 73hp. The T64 had a grille that consisted of eight oval slots. Above the grille there was a round badge with a P in the middle and on the doors there was a Homer badge. This model was sold as either the Prince Homer T64 or the PMC T64.
 The second model was the T640, which was sold as the Nissan Homer T640. This vehicle had the same grille and front badge as the T64, but on the doors it now says Nissan Homer. It continued to use the Prince G-1 engine. This model was built from 1966 until August 1968.
The third version was called the T641, and this model was sold as either the Nissan Homer T641 or the Datsun Homer T641, depending on where it was sold. This model has the "cat's whiskers" grille, consisting of three horizontal slots on each side. This model has a wide wings shaped badge on the front with an N in the middle. The door badges say either Nissan Homer or Datsun Homer. Datsun Homer versions have a rather crude Datsun badge that is pop-rivetted to the front of the truck, just above the wings badge. This model no longer has the Prince G-1 engine and instead has the Nissan R series engine, which is a 1595cc OHV 4 cylinder engine that produces 81hp. This model was built from September 1968 through until August 1972.
The fourth version was the T20, which was sold as either the Nissan Homer T20, the Datsun Homer T20 or the Nissan Cabstar T20. This model had a grille similar to the T641 "cat's whiskers" grille, but there was a slight alteration. On the T641 the indicator was shorter and sat at the side of the grille and was as wide as the grille slot it sat in. On the T20 the indicator is much taller and it is the height of the bottom two grille slots. This model has a different engine again, and now has the Nissan J16, which is a 1567cc OHV 4 cylinder engine which produces 81hp. This version was built from September 1972 until January 1976.
 There was another version of the Homer, which was the T642. The T642 was built at the same time as the T641, and was a 1.5 ton version rather than a 1.25 ton. The only visual difference was that it had a 1.5ton badge under the Homer badge.
 A delivery van version was built of all of the different Homer versions, which was designated either the V64, V640, V641 or V20. There was no V642.
 So, during it's life it was sold as either a Prince Homer, a PMC Homer, a Datsun Homer, a Datsun Cabstar, a Nissan Homer or a Nissan Cabstar. Production of the T20 Homer ceased in January 1976, when it was replaced with the all new F20 Homer.
